Tivoli Storage Manager for Windows Quick Start


Changes for Version 4 Release 1--July 2000

The following changes have been made for Version 4:

Support for Mobile Clients
This enhancement allows mobile users to back up files and make subsequent backups to the portion (a subfile) of the file that has changed, rather than the entire file. This type of backup allows remote or mobile users using modems with limited bandwidth to reduce connection time, network traffic, and the time it takes to do a backup. This enhancement also uses encryption to protect clients' data.

Support and Enhancements for Windows 2000
Removable Storage Manager (RSM) is a service included with Windows 2000 that facilitates communication among applications, robotic changers, and media libraries. It enables multiple applications to share local robotic media libraries and tape or disk drives, and manage removable media with a single-server system. RSM is managed by using a Microsoft Management Console (MCC) console.

Managed System for SAN Environments
This enhancement supports LAN-free data movement in storage area network (SAN) environments. Support is currently limited. The support allows client data to move directly from the client system to a server-managed storage device on the SAN, instead of moving first from the client system to the server over the LAN and then to the device. This enhancement reduces data movement on the LAN so that more bandwidth is available to other applications. This enhancement also increases tape library sharing for multiple TSM servers.

Storage Area Network (SAN) Tape Library Sharing
Tivoli Storage Manager takes advantage of SAN-attached tape libraries by sharing devices among TSM servers that use the same operating system. One of the servers acts as the library manager and the other servers are library clients.

Licensing
A client is now licensed as a managed system. A managed system can be a client or server that requires backup services from the TSM server. Each managed system that moves data to and from storage over a local area network requires a Managed System for LAN license. Each managed system that moves data to and from storage over a storage area network requires a Managed System for SAN license. The following table lists changes to license names:

Former name Current name Notes
Client Connections Managed System for LAN and Managed System for SAN A managed system that moves data to and from storage both on a LAN and on a SAN, requires only the Managed System for SAN license.
